Dental implants require regular maintenance similar to natural teeth, as neglect can lead to infections like peri-implantitis, which can result in bone loss and implant failure. Patients are advised to follow specific oral hygiene guidelines, including proper brushing, flossing, and the use of antimicrobial rinses, to maintain their implants effectively. Regular professional cleaning and attention to potential issues like mucositis are crucial for the longevity and health of dental implants.
